HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 683,131, datedSeptember 24, 1901. Application filed August 17, 1899. Serial No. 727,588. (No model.)

To aZZ whom it may concern.-

Be it known that I, EMERICH VON MARsov- SZKY, a subject of the Emperorof Austria- Hungary, residing at Bulyovszkyutcza 23, Budapest VII,Austria-Hungary,have invented certain new and useful Improvements inHorseshoes, of which the following is a specification.

The known disadvantages of the ordinary horseshoes fastened to the hoofbya number of nails have for a long time led to efforts to design ahorseshoe which can be easily taken off and exchanged. This is desirablefor many reasons. The nailing on of the shoe always materially weakensthe hoof. Further, the horseshoe is worn out more rapidly than the hoofgrows, so that in nailingon the former holes frequently have to be used.Most diseases of the hoof result from the nailing on, which latter alsoalways requires the assistance of an expert shoeing-smith, whichassistance cannot always be obtained.

0n observing the step of an unshod horse it will be found that when thehoof is planted upon the ground it extends laterally thatis to say,becomes broader-and reassumes its original shape again when the hoof israised. This change of form, which takes place at every step, is acircumstance requiring special construction of the horseshoe. The shoeought to permit the said change of form. As long as this condition isnot fulfilled any method of fastening the shoe is unsuitable.

In the horseshoe to which the present in vention relates projections ofthe said shoe engage or dovetail with supporting parts fastened to thehoof in such a manner that lateral expansion of the hoof can take placeon same being planted upon the ground, and secure connection between theprojections and the supporting parts is possible.

In the annexed drawings one form of the new horseshoe is represented asan example.

Figure 1 is a plan view; Fig. 2, a section on the line F F in Fig. 1;Fig. 3, a section on the line G G in Fig. 1, and Fig. 4 a section on theline H H in Fig. 2.

In the form of construction represented in the drawings twooppositely-placed supporting parts 6 have dovetail-like guides or slots71. transverse to the hoof, in which slots the dovetail projections d don the upper faces of the sides of the shoe can slide. As the centralline of the guide projections lies in the same direction as the hoofexpansion, it follows that the said expansion is not hindered. Toprevent the shoe from sliding off laterally, acatch 76, witha projectingboss '5, is pivoted to the toe-cap (Z of the shoe, Figs. 2 and 3. Thesaid boss 1 enters a suitable recess in the support 6 in front of theh0of,'and thus prevents the slipping off 'of the shoe. In ordertopreventthe undesired detachment of the catch it, some suitable safetydevice can be provided. In the example represented herewith the saidsafety device consists of a bar Z and having its end revolving aroundits longitudinal axis and bent sidewise. The said bar is let into thebody of the shoe and when turned holds the end of the catch 7c by meansof its hooked end .5. To open the safety device, the arm m of the bar Zis turned sidewise, so that the hook 8 turns laterally from in front ofthe catch 76. On the latter being opened the shoe can be taken off bysliding it sidewise from the hoof.

In order to adapt the shoe to different sizes of hoof and with a View tothe growing of the latter, the projections d d can be made adjustable inthe direction of length of the shoe, as shown in the drawings, by thesliding piece 01 being made separately from the shoe and integral with aplate t, adapted to slide in a suitable groove in the shoe and adaptedto be fastened in place by means of screws 92.

I declare that what I claim is--= 1. The combination with supportsadapted to be fastened to the hoof, of a horseshoe having projectionsadapted to slidingly dovetail with said supports fastened to the hoof insuch a manner as to permit of lateral expansion of the hoof, and meansfor securing the connection between the said projections and the saidsupports.

2. The combination with supports 6 adapted to be fastened to the hoofand having dovetail slots 72 in a direction transverse to the hoof, of ahorseshoe having dovetailprojections d (Z adapted to engage in saidslots, and means at the too for securing the shoe against lateralsliding upon the hoof, substantially as and for the purpose described.

In witness whereof I have signed this specification in the presence oftwo witnesses.
